power pack repair
Steve G. IF YOU ARE SURE IT'S LEAKING AT THE PRIORITY VALVE! I personally have NOT disassembled the power pack, but looking at the parts manual, FIG 113, Items 44-49 is the priority valve. ALTHOUGH not much room to work, you'd have to remove all the hydraulic fluid, remove the reservoir top and remove the priority valve, from the inside of the reservoir, with a socket, replace the two o-rings Items 45 and 46. Re-install the valve, fill reservoir with H-5606. Then check for leaks. Again I have NOT preformed this type maintenance but looks fairly simple.
